Researchers have recently achieved significant advances in deep learning techniques, which in turn has substantially advanced other research disciplines, such as natural language processing, image processing, speech recognition, and software engineering. Various deep learning techniques have been successfully employed to facilitate software engineering tasks, including code generation, software refactoring, and fault localization. Many studies have also been presented in top conferences and journals, demonstrating the applications of deep learning techniques in resolving various software engineering tasks. However,although several surveys have provided overall pictures of the application of deep learning techniques in software engineering,they focus more on learning techniques, that is, what kind of deep learning techniques are employed and how deep models are trained or fine-tuned for software engineering tasks. We still lack surveys explaining the advances of subareas in software engineering driven by deep learning techniques, as well as challenges and opportunities in each subarea. To this end, in this study, we present the first task-oriented survey on deep learning-based software engineering. It covers twelve major software engineering subareas significantly impacted by deep learning techniques. Such subareas spread out through the whole lifecycle of software development and maintenance, including requirements engineering, software development, testing, maintenance, and developer collaboration. As we believe that deep learning may provide an opportunity to revolutionize the whole discipline of software engineering, providing one survey covering as many subareas as possible in software engineering can help future research push forward the frontier of deep learning-based software engineering more systematically. For each of the selected subareas,we highlight the major advances achieved by applying deep learning techniques with pointers to the available datasets i

A nanocrystal-molecule complex composed of CdSe donor and Rhodamine B (RhB) acceptor is prepared to investigate the effect of accepter-donor ratio on the Fo?rster resonance energy transfer (FRET) process. To highlight the FRET process， the energy level alignment between CdSe and RhB is purposefully designed and CdSe nanocrystal is coated with a wide band-gap ZnS shell. The carrier dynamics is observed via combined spectral analysis. The results reveal clear FRET process between the CdSe donor and RhB acceptor. The FRET is enhanced by increasing RhB/CdSe ratio and a gradual saturation will be present at high RhB concentration.

CZTSSe thin films were prepared using the sol-gel method， and the crystal morphology of the CZTSSe films were improved by Mg doping. The prepared films were characterized using techniques such as XRD， Raman spectroscopy， SEM， and UV-Vis spectroscopy. The results showed that Mg replaced Zn in the CZTSSe lattice， forming the CMZTSSe phase. As the Mg doping concentration increased， the grain size initially increased and then decreased. After Mg doping， no additional impurities are *** the Mg doping concentration was 0.1， the film exhibited the optimal crystal morphology， narrowest peak width， largest grain size， the best light absorption properties smoothest and most compact surface， which is favorable for use as an absorber layer in solar cells.
